Embodiment 1

[0041] Aiming at the problems existing in the prior art, Embodiment 1 of the present invention provides a method for establishing an automatic neighbor relationship, which is applicable to various current TDD (Time Division Duplexing) mobile communication networks and FDD (Frequency Division Duplexing) mobile communication networks. Duplex, frequency division duplex) mobile communication network, such as LTE system, etc.; such as figure 2 As shown, the method may include the following steps:

[0042]Step 201, after the terminal device is attached, if it finds an unknown neighbor cell during the movement process, it will report a measurement report to the serving base station (that is, the serving eNodeB), and the measurement report will carry the unknown neighbor cell (hereinafter referred to as the unknown neighbor cell is the PCI of the target cell), and the serving base station receives a measurement report carrying the PCI of the target cell from the terminal device.

Embodiment 2

[0061] Based on the same inventive concept as the above-mentioned method, an embodiment of the present invention also provides a system for establishing an automatic neighbor relationship, such as image 3 As shown, the automatic neighbor cell relationship establishment system at least includes: serving base station 11, target base station 12 and management station 13, wherein:

[0062] The serving base station 11 is configured to receive a measurement report from the terminal device, and the measurement report carries the physical layer cell identity PCI of the target cell; if the serving base station 11 does not currently establish a neighbor relationship with the target cell, Then send a request message for obtaining neighbor cell relationship information to the management station 13, and the request message carries the PCI of the target cell; and,

[0063] receiving a response message from the management station 13 for notifying the neighbor relationship information, and t...

Embodiment 3

[0071] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a serving base station, such as Figure 4 As shown, the serving base station includes:

[0072]The first receiving module 21 is configured to receive a measurement report from the terminal device, and the measurement report carries the physical layer cell identity PCI of the target cell;

[0073] A sending module 22, configured to send a request message for acquiring neighbor relationship information to a management station when no neighbor relationship with the target cell is currently established, and the request message carries the PCI of the target cell The management station uses the PCI of the target cell to determine the neighbor relationship information of the target cell;

[0074] The second receiving module 23 is configured to receive a response message from the management station for notifying neighbor relationship information, and the response messa...

Abstract

The invention discloses a method, system and equipment for automatic neighbor relation establishment. The method comprises the steps that a serving base station receives a measurement report, which carries a PCI (physical cell identifier) of a target cell, from a terminal device and sends a request message, which is used for obtaining neighbor relation information and carries the PCI of the target cell, to a management station if a neighbor relation with the target cell is not established currently, and the management station determines the neighbor relation information of the target cell by using the PCI of the target cell; and the serving base station receives a response message, which is used for informing the neighbor relation information and carries the neighbor relation information of the target cell, from the management station and establishes the neighbor relation with the target cell by using the neighbor relation information of the target cell. According to the method, the system and the equipment, the process for establishing automatic neighbor relations can be simplified, the number of messages during the establishment of the automatic neighbor relations is reduced, the time for establishing the automatic neighbor relations is reduced, and the handover success ratio of terminal devices is increased.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and equipment for establishing an automatic neighbor relationship. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, the establishment of the neighbor relationship is very complicated, and it is difficult to manually establish the neighbor relationship. Therefore, ANR (Automatic Neighbor Relation, automatic neighbor relationship) is currently used to realize the neighbor relationship Established to reduce manual handling of neighbor relationships, increase the number of successful handovers, and reduce dropped calls due to lack of neighbor relationships. [0003] Such as figure 1 As shown, it is a schematic diagram of establishing a neighbor relationship based on ANR in an LTE system, and the process includes: [0004] Step 1. After the terminal device is attached, if it finds an unknown neighbor cell dur...
